gravitational time delay

The Shapiro delay.

Since gravitational waves have not been directly detected, we don't have any data on the Shapiro delay for gravitational waves.

This is slightly higher, but statistically indistinguishable, from the mass of PSR J1614-2230, which was measured using the Shapiro delay.

He predicted a relativistic time delay (Shapiro delay) in the round-trip travel time for radar signals reflecting off other planets.

Shapiro delay must be considered along with ranging data when trying to accurately determine the distance to interplanetary probes such as the Voyager and Pioneer spacecraft.

By measuring this delay, known as the Shapiro delay, astronomers determined the mass of PSR J1614-2230 and its companion.

In general relativity and other metric theories of gravity, the Shapiro delay for gravitational waves is expected to be the same as that for light (and neutrinos).

This delay is a consequence of general relativity known as the Shapiro delay, and the magnitude of the delay is dependent upon the mass of the white dwarf companion.

As these pulses, which originate from the rotation of the neutron star, passed by the companion white dwarf, their timing was delayed due to the highly warped nature of spacetime-an effect known as Shapiro delay.

Closely related to light deflection is the gravitational time delay (or Shapiro delay), the phenomenon that light signals take longer to move through a gravitational field than they would in the absence of that field.

However in theories such as Teves and other modified GR theories which reproduce Milgrom's law and avoid the need for dark matter, the Shapiro delay for gravitational waves is much smaller than that for neutrinos or photons.

After observing the system for two and a half years, four independent tests of general relativity were possible, the most precise (the Shapiro delay) confirming the general relativity prediction within 0.05% (nevertheless the periastron shift per orbit is only about 0.0013% of a circle and thus it is not a higher-order relativity test).
